informing decisions in chronic critical illness: a randomized control trial (rct)

Conditions: Chronic Critical Illness; Prolonged Mechanical Ventilation

Summary: the purpose of this study is to test a communication intervention to support family decision-making for patients with chronic critical illness.

increasing use of intensive care therapies by an aging population has created a new medical syndrome - "chronic critical illness" - encompassing multi-system derangements, recurrent complications, and protracted/permanent dependence on mechanical ventilation and other life-supports. numbering \>100,000 at any point in time, the chronically critically ill are a growing population of older adults and a serious national health problem. annual expenditures for these patients are estimated at $24 billion, mostly for patients ≥ 65 years old. yet 6-month mortality rates exceed those for most malignancies, impairments are severe among survivors, and return to the community is rare. descriptive research has identified domains of information that are important for decision-making by patients/families about continuation of treatment in the chronic phase of critical illness, but has also revealed that decisions are often made without this information or patient goals of care as a context. in acute critical illness, scheduled, structured meetings and printed informational aids are effective for intensive care unit (icu) families, but no study has tested an intervention to inform and support decision-making about chronic critical illness. this study is a randomized, controlled, multi-center clinical trial of such an intervention. specific aims are: (1) to evaluate the impact on family- and patient-focused outcomes of a proactive program of protocolized, interdisciplinary, informational support meetings led by a palliative care physician, plus a printed informational aid, for families of chronically critically ill patients; and (2) to evaluate the impact of this intervention on utilization of critical care resources for the chronically critically ill. we hypothesize that as compared to usual care plus the printed aid, this intervention will effectively inform decision-making, improve family well-being, promote discussion of preferences for patient goals of care, and optimize critical care resource utilization, without increasing patient mortality.
